Unidentified
On the public record, and still open. A claim, paper, or film — not a finding that it was ours, and not a finding that it was not.
What was claimed
Thousands along the Hudson reported a silent, V-shaped “flying city” of lights, low enough to hide the stars behind it. Some nights it was a prank of ultralights. Some nights it was not so easy.
What is on the record
This file is a working record — a report, not a verdict. Official paper, if any, is linked where we have it.
From 1983 to 1986 the towns from Yorktown to Newburgh generated one of the largest report loads in American files. Witnesses described a huge boomerang or triangle, often with multi-colored lights, drifting at a few hundred feet, sometimes stopping over a parkway. Police officers filed reports. J. Allen Hynek’s colleagues at CUFOS investigated.
A group of pilots flying ultralights in formation later claimed some of the displays. They do not claim all of them, and they do not claim the nights when a solid dark form blocked the sky. Stormville Airport radar was occasionally involved.
The Hudson Valley file is a mass of letters, 911 calls, and police logs. It is also a warning about how a clever prank and an unidentified craft can occupy the same county in the same decade.
Could this have been ours?
The known sky, that night.
Satellites were already up. The station was not. Starlink was not.

Aircraft, balloons, meteors
Landing lights, flares, lanterns, reentries, fireballs. They are on the known sky. They do not close a file by themselves — they are what a serious look has to hold the claim against.
